Anomalous Photoluminescence in Undoped and Mn2+-Doped 2D Hybrid Lead Halide Systems

Abstract Two-dimensional (2D) hybrid lead halide systems have emerged as promising materials for optoelectronic applications due to their remarkable optical properties and enhanced moisture stability. However, photoluminescence (PL) from such 2D samples has been reported to vary...

Transformative Materials Research: Defining Conceptual Change across Scales

Abstract What qualifies as transformative materials research? In this Viewpoint, we use “transformative” to denote work that forces revision of underlying assumptions, enables generalization across systems, or reveals regimes inaccessible to existing frameworks. The term is widel...
